You could use a parameterized test:

import static org.junit.Assert.assertEquals;

import java.util.Arrays;
import java.util.Collection;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import org.junit.runners.Parameterized.Parameters;

@RunWith(Parameterized.class)
public class MyParameterizedClassTest {

  private string promptNameOrg;

  public MyParameterizedClassTest(string testParameter, string expectedParameter) {
    this.promptNameOrg = testParameter;
    this.expected = expectedParameter;
  }

  // creates the test data
  @Parameters
  public static Collection<Object[]> data() {
    Object[][] data = new Object[][] { { "20129142\\1234", "1234" }, { "80808080\\159;20129142\\1234", "1234" } };
    return Arrays.asList(data);
  }

  @Test
  public void extractSimplePromptNameFindsLastPartOfString() {
    String simplePromptName = extractSimplePromptName(this.promptNameOrg);
    Assert.assertEquals(this.expected, simplePromptName);
  }

  // extractSimplePromptName omitted
}

There can only be one @Test in such a class, though.
